User Testing - finalising my model of an x-ray machine #Blender #EuroPCR
This entry is part 20 of 20 in the series My X-Ray model project

So you may remember that we started this project with an overall plan that follows the PMBOK (Project Management Body of Knowledge) approach to remodel a 3D likeness of an  x-ray machine that I first modeled a year ago for a presentation at EuroPCR 2016 – the official annual meeting of the European Association of Percutaneous Cardiovascular Interventions (EAPCI) and the world-leading Course in Interventional Cardiovascular Medicine. Here is the diagram of the plan:

I now feel that I have reached the Close part of the plan (at least until my skills improve and I can make a third attempt AND also given my my brother in law will be attending EuroPCT 2017 and I can create images for him using this now instead of my old model). So I need to do the Quality testing. My test user is obviously my brother-in-law Glenn. He had sent me some photos of the angles that he wanted to display the model for his presentation and asked me to add a patient. This was what I sent back..

The first two pictures suited his needs but the last two did not. He needed the top part to be closer to the patient. The reason for this was that it meant less radiation due to inverse square law. Then he gave me a bit of knowledge that was new to me: the top part can move to extend downwards.

Ah!

Oh!

I had the image intensifier as a solid part of the arm. This is what happens when an artist does not have a proper technical understanding of a machine. So I needed to disconnect it and stretch it and then assemble it next to, but not as part of, the arm. The reason I needed to stretch it was so that when it lowered it did not suddenly hang in space. This took a little while as I returned to blender. Outcome:

 

 

The response to this : “The 3rd one’s perfect. I’ll use that and the previous cranial ones. Good work.” So it passed testing.

And so more of my graphic work will turn up in Paris at EuroPCR. Cool!

I know that Glenn will give a marvelous presentation and I am happy that I can help in a small way.

Thanks for reading.

Greg

  1. Excellent Greg, well done! The model really comes to light with the addition of the figure – it becomes meaningful. I too have lots of thought diagrams – old fashioned, pen and paper mind maps, in my case. But, I finally know where I am going with my project, what it is, what it might look like, what its story is. A lot of that is due to you and Calmgrove and for that, I thank you both. Looking forward to your next project.


    1. I must admit that I love pen and paper mind-maps and use them an awful lot. I am also stoked that I have in some way helped you with your project. I can’t wait to see what it is. I’m thinking about making doors for my next project. A series of doors – perhaps art deco or something.


      1. I’m a fan of Art Deco and Art Nouveau. I prefer form over function. Doors sound like great project as does windows. Keep up the great work.


  2. Great stuff man! The human figure really adds more to the overall price.
